MASM7 is a mitofusin activator that concentration-dependently increases Mito AR (Mitochondrial Aspect Ratio; EC50=75nM) in MEF cells. MASM7 directly binds to the HR2 domain of MFN2 (Kd=1.1μM) to activate MFN2 or MFN and induce mitochondrial fusion. MASM7 can be used in research related to mitochondrial function, cellular energy metabolism, and inflammation regulation (such as dental pulp repair)[1-4].
In vitro, MASM7 (1μM) was used to treat endothelial progenitor cells cultured with conditioned medium from sodium caffeine benzoate-incubated RAW264.7 cells for 24 hours. MASM7 enhanced the angiogenic capacity of endothelial progenitor cells, reversed mitochondrial swelling, reduced reactive oxygen species production, increased mitochondrial membrane potential levels, elevated OPA1, p-AKT, and p-GSK3β protein expression, and decreased DRP1 protein expression[5]. MASM7 (1μM) was used to treat human bone marrow mesenchymal stem cells transfected with a short hairpin-FoxO1 plasmid and induced with BMP-2 (10ng/ml) for 7 days. MASM7 significantly reduced cytoplasmic mitochondrial DNA levels, decreased mitochondrial membrane potential levels, increased adenosine triphosphate content, enhanced mitochondrial autophagy, promoted cell proliferation and migration, reduced apoptosis, and increased extracellular matrix calcium deposition[6].
In vivo, MASM7 (10μg in 10μl; once daily) was administered via intrathecal injection to rats with a skin/muscle incision and retraction model for seven consecutive days. MASM7 alleviated skin/muscle incision and retraction-induced mechanical allodynia, improved mitochondrial function, reduced reactive oxygen species accumulation, and mitigated pyroptosis of gamma-aminobutyric acid-ergic neurons in the spinal cord[7]. MASM7 hydrogel (20mM/1ml; 2μl/tooth; single treatment) was topically applied to the teeth of a rat model of pulpitis, followed by ultraviolet light (405nm, 50mW/cm²) irradiation for 30 seconds. The MASM7 hydrogel promoted the repair of dental pulp tissue under inflammatory conditions by regulating macrophage polarization and scavenging reactive oxygen species[8].
